holding back innovation? i think there is one sense it is not, and i will come back to the in one sense it is, and i will come back to the recycling point. i remember recently picking up one of these water bottles that you buy at the store, crystal springs, or whatever, and it says something about this eco- friendly water bottle, thinner walls, shorter, lighter cap and all these things, and i think all these people -- i think aren't these people wonderful. wait a minute, why did they do that? maybe it has to do with higher oil prices, lower transportation costs, and if they jump on the green bandwagon and innovated in part because they thought they would get a larger share of the market, i guess in that sense green does stimulate innovation. of them that, i think it is not a main driver -- other than that, i think it is not a main driver. at all has to do whether or not it is profitable.
